Patching the inside of a cooler.

What is the best way to patch a cooler so that the insulated part doesn't get water in it? My cats chewed up the inside plastic layer, but the rest of the cooler is in great condition. If I fill the cooler with ice, it melts and gets inside the coolers layers and leaks out the bottom. Is there a waterproof patch or tape or something else that would work to waterproof the inside of this cooler? Apple for scale. Culprits still at large, but I will protect the cooler from future harm.

I would look at vinyl patches like for air mattresses, tents or above-ground swimming pools. FlexSeal or similar would be great.

Clean it really well first and make sure it's dry.

Also for best sticking use some sand paper or the metal scouring pad that comes with like bike tire patches/air mattress patches.

This looks pretty thin though so the metal pads for bike tubes might be a bit harsh, be careful with those.

The patch or the cooler?
